New data are available in Journal Citation Reports

In March of 2013, we began production of the new JCR data. Over 55 million cited references were extracted from items indexed in the year 2012. Over 283,000 lines of algorithms are used to analyze and aggregate these references for the JCR metrics.

10,854 titles appear in the first release of JCR. The full list of titles is available here.

379 journals will be posting their first Journal Impact Factor this year. See the list here.

The JCR Production team has also prepared information regarding the suppression of journals from the JCR. A longer post on this subject will follow in the next few days. In the meanwhile, users concerned about this subject can access information here - click on the link "Learn more about the JCR Suppression Process".

I do not understand the mean of the IMPACT FACT. Some journals are good, but some are just the IMPACT FACT, with low quality paper, eg. Plant Molecular Biology Report. The citation to this kind of journals were just self-citation.

The Journal Citation Reports presents metrics (including,but not limited to the Journal Impact Factor) for journals that are covered in the Science Citation Index-Expanded and/or the Social Sciences Citation Index. This is not intended to be an all-inclusive set of "good" journals, but a curated, selected collection of journals that represent the world's scholarly literature. See this: http://wokinfo.com/essays/journal-selection-process/ for more infomation about journal selection - both why and how.

Complete and consistent receipt of issues is a critical requirement for the production of JCR data. For the past few years, during JCR production, we had identified missing issues from 2009, 2010, 2011 and 2012 for Iranian Journal of Immunology and we were unable to publish a Journal Impact Factor. We have successfully loaded 2010 and 2011 complete content now and updated metrics are visible in the JCR Notices file: http://admin-apps.webofknowledge.com/JCR/static_html/notices/notices.htm

When we reload the JCR data in September of this year, these numbers will be available in the product.

I would encourage you to contact our Publisher Relations team (ts.agpublisherrelations@thomsonreuters.com) to arrange for electronic delivery of content to avoid further gaps in coverage in Web of Science or JCR.

We will send them again as soon as possible Many thanks for he information With best A Ghaderi IJI Editor www.iji.ir

I wanted to know whether the journal Electronic journal of Geotechnical Engineering (EJGE) having ISSN 1089-3032 will be awarded an impact factor in 2015?

The awards page of EJGE journal mentions it as a High Impact Factor journal awarded by Thomson Reuters and wanted to know if it has been selected to be awarded an impact factor. I have observed number of papers in EJGE being cited in other high IF journals.

Finally, the journal is already being indexed by Scopus, hence I wanted to know if it is also being indexed by Thomson Reuters.
